BOILER COMPOUND.

SPECIFICATION forming part of Letters Patent No. 720,267, dated February10, 1903. Application filed May 10,1901. Renewed January 2, 1903. Seri lN 137,567. (No specimens.)

To all wham it may concern:

Be it known that I, JOSEPH LOUDENSLAGER, of Tiffin,in the county ofSeneca,State of Ohio, have invented acertain new and useful BoilerCompound, of which the following is a complete specification.

The object of my invention is to produce an improved compound forpreventing incrustation of boilers which is economical and efficient inuse.

My compound is composed of the following ingredients in the proportionsspecified: two pounds of catechu, gambier, or japonica; one pound ofpotash, preferably made from woodashes; two pounds of soda-ash,a nd onepound of German or Spindel salts.

The term German salts is one which is used commercially to denominatethe salts of acertain German spring,known also as Spindel salts, ofwhich the following is an analysis: calcium sulfate, .020 grams; sodiumbicarbonate, .360 grams; sodium chlorid, .180 grams; sodium sulfate,.440 grams; total, 1,000 grams.

In the appended claim I shall use the term catechu in a generic sense toinclude a substance variously denominated catechu, gambier, andjaponica.

The composition is prepared as follows: The gambier, catechu, orjaponica is first steamed for two hours, and then the other ingredientsare added and the mixture is steamed for one hour longer. Finally enoughwater is added to reduce the mixture to a liquid state, in which it canbe filtered or strained. After filtration the compound is ready for use.

In practice one gallon of the compound to every fifty-horse power ofboiler should be supplied at one time to the boiler after it is cleaned.The composition should be supplied to the boiler each Week, and theboiler should be cleaned every two weeks.

The proportions of the ingredients specified may be varied somewhat; butI obtain the best results through the employment of the ingredientsspecified and substantially in the proportions named.

' The application of heat as specified is conveniently and preferablyobtained by steaming; but other methods of applying heat and at the sametime keeping the ingredients moist might be employed.

What I claim is- A boiler compound consisting of catechu, potash,soda-ash and German salts, combined substautially' in the manner and inthe proportions specified.

In testimony of all which I have hereunto subscribed my name.

JOSEPH LOUDENSLAGER.
